"[Shelters are] doing so much on so little, to be honest, and a lot of it's just for the love of the dogs and trying to help the community and trying to help the animals," said goaltender Jake Allen, whose dog Marvin was adopted from Gateway Pet Guardians.

Tuesday's photoshoot was just the start. Allen, Carter Hutton and Alex Pietrangelo all brought their dogs in for the photoshoot, while Scottie Upshall, Patrik Berglund, Robby Fabbri and Joel Edmundson took their photos with adoptable dogs.

In addition to purchasing their Pucks for Paws calendar, fans at Barkin' for the Blues can meet adoptable pets on the concourse. Proceeds will benefit Five Acres Animal Shelter, Gateway Pet Guardians and Stray Rescue of St. Louis.

"All of these dogs and every one of them that I've met at a shelter have been pretty amazing," Allen said. "And Marvin is so gentle and nice, especially with our little daughter now. It's pretty amazing."
